Cisco Mesh Access Points User Manual

• When voice is operating on a mesh network, calls must not traverse more than two hops. Each sector
must be configured to require no more than two hops for voice.
• RF considerations for voice networks are as follows:
◦ Coverage hole of 2 to 10 percent
◦ Cell coverage overlap of 15 to 20 percent
◦ Voice needs RSSI and SNR values that are at least 15 dB higher than data requirements
◦ RSSI of -67 dBm for all data rates should be the goal for 11b/g/n and 11a/n
◦ SNR should be 25 dB for the data rate used by client to connect to the AP
◦ Packet error rate (PER) should be configured for a value of one percent or less
◦ Channel with the lowest utilization (CU) must be used
•
On the 802.11a/n or 802.11b/g/n > Global parameters page, do the following:
◦ Enable dynamic target power control (DTPC).
◦ Disable all data rates less than 11 Mbps.
•
On the 802.11a/n or 802.11b/g/n > Voice parameters page, do the following:
◦ Load-based CAC must be disabled.
◦ Enable admission control (ACM) for CCXv4 or v5 clients that have WMM enabled. Otherwise,
bandwidth-based CAC does not operate properly.
◦ Set the maximum RF bandwidth to 50 percent.
◦ Set the reserved roaming bandwidth to 6 percent.
◦ Enable traffic stream metrics.
•
On the 802.11a/n or 802.11b/g/n > EDCA parameters page, you should do the following:
◦ Set the EDCA profile for the interface as voice optimized.
◦ Disable low latency MAC.
•
On the QoS > Profile page, you should do the following:
◦ Create a voice profile and select 802.1Q as the wired QoS protocol type.
•
On the WLANs > Edit > QoS page, you should do the following:
◦ Select a QoS of platinum for voice and gold for video on the backhaul.
◦ Select allowed as the WMM policy.
•
On the WLANs > Edit > QoS page, you should do the following:
◦
Select CCKM for authorization (auth) key management (mgmt) if you want to support fast roaming.
•
On the x > y page, you should do the following:
